CRUST

CRUST - is the outermost and thinnest layer of the Earth (around 5 to 70 km deep).

MANTLE

MANTLE is the thickest layer of the earth. The semi-liquid sort of like a malleable plastic and makes up 84% of earth's volume.

OUTER CORE

OUTER CORE - is located beneath the mantle (2,200 km thick). It is made up of hot, molten iron and nickel (up to 5,000°C). This layer spins as the planet rotates and creates Earth's magnetic field, which helps to protect us from the Sun's solar radiation.

INNER CORE

INNER CORE - is the deepest layer of the Earth. It’s about 1,230 to 1,530 km thick and can be as hot as the surface of the sun, about 5505 °C. Like the outer core, it is made up of iron and nickel, but due to high pressure, these metals remain solid.
